Brain rhythm associated with learning linked to running speed

June 28, 2011

Rhythms in the brain that are associated with learning become stronger as the body moves faster, neurophysicists at the University of California, Los Angeles, have found.

The experiment was performed by measuring electrical signals from hundreds of mice neurons using microwires, the researchers said. Nearly a hundred gigabytes of data was collected every day.

Analysis of the data showed that the gamma rhythm, a fast signal that occurs while concentrating or learning, gradually grew stronger as the mice moved faster.

Does this mean movement or exercise could influence the learning process? The researchers said it is too early to tell.
